Description

Technical Field

[0001] The invention relates to a digital CRPS power supply, in particular to a plug-in digital CRPS power supply and system for realizing different power combinations, belonging to the field of intelligent digital power supply. Background Art

[0002] Digital CRPS power supply is a power-controllable digital power supply used by servers. It matches the power requirements of different servers and is a new type of power supply that can optimize power configuration for unstable power grids. Currently, digital CRPS power supplies all use real-time measurement and control of electrical parameters at the output or input end. No matter which stage is improved, it is still essentially a local power supply digital control. There is no mutual computing power support between power supplies. If the local digital control system fails, the continuous output of the power supply cannot be guaranteed, such as a failure of the conversion card. In addition, different power requirements have different conversion capabilities and ranges for the conversion card, and the use of fixed plug-in cards cannot meet diverse power requirements. Summary of the invention

[0003] Based on the above problems in the prior art, the present invention considers the following two points: first, a plug-in detection circuit is used at the input end, and a plug-in converter is used at the output end; second, a remote communication control circuit is provided at the output end, which has both local numerical control and plug-in sharing scheduling of the remote server.

[0004] In view of the above considerations, the present invention provides a plug-in digital CRPS power supply for realizing different power combinations, comprising a CRPS power supply body, an input end current detection circuit, an input end voltage detection circuit, an output end current conversion circuit and an output end voltage conversion circuit connected to the CRPS power supply body, and a local control circuit connected to the output end current conversion circuit and the output end voltage conversion circuit, wherein the local control circuit communicates with a remote main server, wherein;

[0005] The four types of circuits, namely, the input-end current detection circuit, the input-end voltage detection circuit, the output-end current conversion circuit and the output-end voltage conversion circuit, are at least two each (for power group matching), and are all plug-in twin circuits, that is, at least two circuits of the same structure, at least one for local use and at least one for shared services, and the four types of circuits are all plug-in circuits that can be used in the power line in a hot-swappable manner. The local control circuit controls the output-end current conversion circuit and the output-end voltage conversion circuit according to the power demand distribution in the local power grid and the real-time detection results of the input-end current detection circuit and the input-end voltage detection circuit to distribute power that is compatible with the power demand distribution;

[0006] When at least one of the four types of circuits in at least one local area in the power grid fails, the local control circuit controls the twin circuit of the failed circuit to use the sharer or other non-sharer to replace the work. If both the sharer and the other non-sharer fail, the local control circuit sends a support request to the remote main server, and the remote main server searches for the current idle circuits (i.e., non-working shared and non-sharers) of each local power grid in the main power grid, as well as the corresponding allocated capabilities, and dispatches the corresponding type of circuit to provide the corresponding circuit function to the requester.

[0007] Optionally, the detection results include instantaneous apparent power at the input end of the CRPS power supply body, instantaneous active power at the input end of the CRPS power supply body, instantaneous reactive power at the input end of the CRPS power supply body, instantaneous power factor of the CRPS power supply body, instantaneous input voltage of the CRPS power supply body and instantaneous input current of the CRPS power supply body.

[0008] Optionally, the input-end current detection circuit and the input-end voltage detection circuit both communicate with the remote main server, and periodically send detection results to the local control circuit and the remote main server, wherein each sharer is connected to a multi-way hub switch for connecting to sharers in other corresponding circuits of the same type, and when one of the non-sharer twin circuits fails, the local control circuit detects periodic data loss, and recognizes the detection result of the previous cycle at the time of the failure as the detection result when the failure occurs, and sends the fault information to the remote main server, and controls the connection of another non-sharer twin circuit or sharer twin circuit to continue real-time detection. At the same time, when both the sharer and the other non-sharer fail, the detection result of the previous cycle at the time of the failure is recognized as the detection result when the failure occurs, and scheduling is performed to continue real-time detection;

[0009] The output current conversion circuit and the output voltage conversion circuit both communicate with the local control circuit and the remote main server, and send control signals to the remote main server for recording in real time. The sharers therein are each connected to a multi-way hub switch for connecting to sharers in other corresponding circuits of the same type. When one of the non-sharer twin circuits fails, the local control circuit detects the data abnormality, and recognizes the most recent control signal as the control signal when the fault occurs, controls the connection of another non-sharer twin circuit or the sharer twin circuit, continues real-time control, and sends the fault information to the remote main server, which can also provide a basis for whether the scheduling is adjustable or not; at the same time, when both the sharer and the other non-sharer fail, the previous control signal at the time of the fault is recognized as the control signal when the fault occurs, and the scheduling is executed to continue the real-time conversion.

[0010] It is understandable that, since the probability of simultaneous failure of sharers and non-sharers is low, it is not necessary to interconnect all sharers in the entire region, and the number of interconnected sharers is selected based on the configuration cost and the historical failure rate data of the region. Due to the lack of periodic data, the remote master server can provide a basis for whether the scheduling is adjustable (that is, the corresponding fault circuit that issued the request cannot be used for scheduling).

[0011] Optionally, the local control realizes the switching connection between the sharers and non-sharers in the four types of circuits through a switching circuit.

[0012] Optionally, the fault information is a short text describing the fault.

[0013] Optionally, the remote main server searches the main power grid for currently idle circuits of each local power grid and the corresponding allocated capacity, and dispatches circuits of corresponding types to provide corresponding circuit functions to the requesting party, specifically including the following steps:

[0014] S1 draws the spatial distribution diagram of four types of circuits and marks the current idle circuits of each local power grid according to the fault information sent by the local control circuit;

[0015] S2 obtains the power consumption history data of the running circuits corresponding to all the current idle circuits in the distribution map, and uses a pre-trained generative adversarial network to identify whether the corresponding power consumption history data of the requester is similar to the power consumption history data;

[0016] S3 randomly selects a similar corresponding idle circuit and calls the idle circuit to provide the requesting party with the corresponding circuit function.

[0017] Optionally, the optimization method of the generative adversarial network includes:

[0018] S2-1 collects historical electricity consumption data of each local power grid, divides part of it into training set and verification set, and uses the remaining part of historical data for training to judge whether it is similar or not. For each remaining part of historical data, the verification set is manually marked to see whether it is similar or not;

[0019] S2-2 builds a generative adversarial network, inputs the training set into the generator, outputs the pseudo-image, selects a historical data for training similarity judgment, inputs the pseudo-image and the data into the judgement, performs training, and uses the validation set to verify and optimize the generator, and so on, selects all the historical data for training similarity judgment, and completes the training of the generator;

[0020] S2-3 then inputs the training set into the trained generator in the manner of S2-2, outputs the pseudo-image, selects a historical data for training similarity judgment, inputs the pseudo-image and the data into the judger for training, and uses the validation set to verify the optimized judger. Similarly, all historical data for training similarity judgment are selected to complete the training of the judger, and finally the generator is discarded, and the judger is used as the optimized model.

[0021] Optionally, the historical data is a real variable function graph of electricity consumption data, with a time span of 1-3 months.

[0022] Therefore, due to the similarity judgment training on a large amount of historical data, similarity judgments can be generated using the judgement machine.

[0023] The present invention also provides a plug-in card-type digital CRPS power supply system for realizing different power combinations, comprising a plurality of any of the above-mentioned plug-in card-type digital CRPS power supplies for realizing different power combinations, and a remote main server communicating with the plurality of plug-in card-type digital CRPS power supplies for realizing different power combinations, wherein the plug-in card-type twin circuits are all plugged into corresponding circuit plug-ins, and the plug-ins are provided with switching circuits and multi-way hub switch connection ports.

[0024] The plug-in card-type digital CRPS power supply and system for realizing different power combinations provided by the present invention have the following beneficial effects:

[0025] Through the design of twin circuits and the main remote server, faults caused by the measurement circuit of input parameters and the conversion circuit of electrical parameters can be quickly connected and the circuits in the power grid can be shared. At the same time, plug-in circuits are used to access the power grid. The switching and sharing of twin circuits make the operation, maintenance and replacement of circuits convenient.

DETAILED DESCRIPTION

[0032] Example 1

[0033] like Figure 1 As shown, the embodiment of the present invention provides a plug-in digital CRPS power supply for realizing different power combinations, including a CRPS power supply body 1, an input end of which is connected to an input end current detection circuit 4 and an input end voltage detection circuit 5, an output end of which is connected to an output end current conversion circuit 2 and an output end voltage conversion circuit 3, and a local control circuit 6 connected to the output end current conversion circuit 2 and the output end voltage conversion circuit 3, wherein the local control circuit 6 is connected to a remote main server 8 ( Figure 2 ) communication, the CRPS power supply body 1 is connected to the local server 7 for power supply.

[0034] The four types of circuits, namely, the input current detection circuit 4, the input voltage detection circuit 5, the output current conversion circuit 2 and the output voltage conversion circuit 3, are all plug-in twin circuits, that is, there are at least two circuits with the same structure, one for local (i.e., non-shared), Figure 1 The reference numerals in the figure include an output terminal current conversion circuit non-sharer 2-1, an output terminal voltage conversion circuit non-sharer 3-1, an input terminal current detection circuit non-sharer 4-1, an input terminal voltage detection circuit non-sharer 5-1) and a shared service ( Figure 1 The reference numerals in the figure include output current conversion circuit sharer 2-2, output voltage conversion circuit sharer 3-2, input current detection circuit sharer 4-2, and input voltage detection circuit sharer 5-2), and the four types of circuits are all plug-in circuits that can be used in power lines in a hot-swappable manner. The four types of circuits include multiple ones, and different currents and voltages can be achieved through different plug-in combinations.

[0035] like Figure 3 As shown, the plug-in twin circuits are plugged into the corresponding circuit plug-in box 9, and the sharer and non-sharer are inserted through the socket 10 on the top. The bottom is provided with an area 12 for installing the switching circuit and a multi-way line switch (such as Figure 1 The first multi-way line collection switch 8-1, the second multi-way line collection switch 8-2, the third multi-way line collection switch 8-3 and the fourth multi-way line collection switch 8-4) and the connection port 11. When the corresponding detection circuit or conversion circuit is inserted into the circuit plug box 9 through the socket 10, it can be plugged with the installed switching circuit in the installation area 12, and connected to the local control circuit 6 through the signal line to realize the working state switching between the sharer and the non-sharer.

[0036] like Figure 2 As shown, multiple regions have multiple digital CRPS power supplies as shown by triangles (see Appendix Figure 1 ), the local control circuit 6 controls the output current conversion circuit 2 and the output voltage conversion circuit 3 according to the power demand distribution in the local power grid (represented by a chamfered rectangle) and the real-time detection results of the input current detection circuit 4 and the input voltage detection circuit 5 to distribute power that is compatible with the power demand distribution.

[0037] When at least one of the four types of circuits in the local grid is used, the input current detection circuit is not shared by 4-1 (such as Figure 2 Taking a fault in a) as an example, the local control circuit 6 controls the input current detection circuit 4 in the twin circuit for the input current detection circuit sharer 4-2 to work instead. If both the input current detection circuit non-sharer 4-1 and the input current detection circuit sharer 4-2 fail (such as Figure 2 In b), the local control circuit 6 sends a support request to the remote main server 8, and the remote main server 8 searches the main power grid for the current idle circuits of each local power grid and the corresponding allocated capacity, and dispatches the corresponding type of circuit to provide the requester with the corresponding current detection function.

[0038] Specifically, if Figure 1 As shown, the input current detection circuit 4 and the input voltage detection circuit 5 are both connected to Figure 2 The remote main server 8 in the communication periodically sends detection results to the local control circuit 6 and the remote main server 8, wherein the respective input current detection circuit sharers 4-2 and input voltage detection circuit sharers 5-2 are respectively connected to the first multi-way hub switch 8-1 and the second multi-way hub switch 8-2, which are used to connect to the sharers in other corresponding circuits of the same type, and when one of the non-sharer twin circuits fails, the local control circuit 6 detects the periodic data loss.

[0039] like Figure 4 As shown, for the fault information, the control signal and the detection result are the vertical coordinate time t (unit s), the signal with the pulse seen in the horizontal coordinate, t1-t3, and the signal did not arrive as expected at t4, indicating a fault, and it was restored at t5 due to switching or scheduling.

[0040] The local control circuit 6 detects the detection result of the previous cycle when the fault occurs. Figure 4 The detection result of the time period t3 in the system is regarded as the detection result of the time period t4 when the fault occurs, and the fault information (i.e. the fault message of the time period t4) is sent to the remote main server 8, and another sharer twin circuit (i.e. the output end current conversion circuit sharer 2-2, the output end voltage conversion circuit sharer 3-2, the input end current detection circuit sharer 4-2, the input end voltage detection circuit sharer 5-2) is controlled to be connected, and real-time detection is continued. At the same time, when both the sharer and the other non-sharers fail, the detection result of the previous cycle at the time of the fault occurrence is regarded as the detection result when the fault occurs, and scheduling is performed to continue real-time detection;

[0041] The output current conversion circuit 2 and the output voltage conversion circuit 3 both communicate with the local control circuit 6 and the remote main server 8, and send the control signal to the remote main server 8 in real time for recording. The sharers therein are each connected to a multi-way hub switch (i.e., the third multi-way hub switch 8-3 and the fourth multi-way hub switch 8-4) for connecting to sharers in other corresponding circuits of the same type. When one of the non-sharer twin circuits (the input current detection circuit non-sharer 4-1 and the input voltage detection circuit non-sharer 5-1) fails, the local control circuit 6 detects the data abnormality, and recognizes the most recent control signal as the control signal when the fault occurs (i.e., the t3 period), controls the connection of the other sharer twin circuit (the input current detection circuit sharer 4-2 and the input voltage detection circuit sharer 5-2), continues real-time control, and sends the fault information to the remote main server 8, which can also provide a basis for whether the scheduling is adjustable or not.

[0042] At the same time, when the input current detection circuit sharer 4-2 and the input voltage detection circuit sharer 5-2 and the input current detection circuit non-sharer 4-1 and the input voltage detection circuit non-sharer 5-1 all fail, the previous control signal at the time of the failure is recognized as the control signal when the failure occurs, and scheduling is performed to continue real-time conversion.

[0043] The remote main server 8 searches the main power grid for the current idle circuits of each local power grid and the corresponding allocated capacity, and dispatches the corresponding type of circuit to provide the requester with the corresponding circuit function, specifically including the following steps:

[0044] S1 draws a spatial distribution diagram of four types of circuits and marks the current idle circuits of each local power grid according to the fault information sent by the local control circuit 6;

[0045] S2 obtains the power consumption history data (i.e., power consumption real variable function graph) of the running circuits corresponding to all the current idle circuits in the distribution graph, and uses a pre-trained generative adversarial network to identify whether the corresponding power consumption history data of the requester is similar to the power consumption history data;

[0046] S3 randomly selects a similar corresponding idle circuit and calls the idle circuit to provide the requester with the corresponding circuit function (such as Figure 2 as shown).

[0047] like Figure 5 As shown, the optimization method of the generative adversarial network includes:

[0048] S2-1 collects historical electricity consumption data of each local power grid, divides part of it into training set and validation set (the ratio of the two is 3:1), and uses the remaining part of historical data for training to judge whether it is similar or not. For each remaining part of historical data, the validation set is manually labeled to see whether it is similar or not;

[0049] S2-2 builds a generative adversarial network, inputs the training set into the generator, outputs the pseudo-image, selects a historical data for training similarity judgment, inputs the pseudo-image and the data into the judgement, performs training, and uses the validation set to verify and optimize the generator, and so on, selects all the historical data for training similarity judgment, and completes the training of the generator;

[0050] S2-3 then inputs the training set into the trained generator in the manner of S2-2, outputs the pseudo-image, selects a historical data for training similarity judgment, inputs the pseudo-image and the data into the judger for training, and uses the validation set to verify the optimized judger. Similarly, all historical data for training similarity judgment are selected to complete the training of the judger, and finally the generator is discarded, and the judger is used as the optimized model.

[0051] As an embodiment, when the remote main server 8 receives the request, it executes steps S1-S2 and can Figure 2 The power usage history data of the operating circuit (i.e., non-sharer) corresponding to the current idle circuit (represented as the sharer in the power supply of the triangle a) in the identification requester is input into the judgment device, and the judgment result is similar, then step S3 is performed to select the similar corresponding idle circuit, and the idle circuit is called to provide the corresponding circuit function to the requester. Since this embodiment is a comparison with the power usage history data of an operating circuit, the random selection can only be, that is, the corresponding idle circuit.
